我试图使用iframes在一个

WebView

html中显示多个html文件

我在html文件中使用以下脚本来调整当前html中iFrame的高度

<body onload="resizeFrames()" link="#bb7722" vlink="#bb7722" alink="#bb7722" > 


    <script type="text/javascript">
        // Firefox worked fine. Internet Explorer shows scrollbar because of frameborder
        function resizeFrames() {
            var all_IFrames = document.getElementsByTagName('iframe');
            i = 0;
            while (frame = all_IFrames.item(i++)) {
                resizeFrame(frame);
            }            
        }
        function resizeFrame(f) {

            f.style.height = f.contentWindow.document.body.scrollHeight + "px";
        }
    </script>

    <iframe width="100%" scrolling="no" frameborder=0 border=0 src="b.html"></iframe>
    <iframe width="100%" scrolling="no" frameborder=0 border=0 src="c.html"></iframe>

我按如下方式加载html文件：

webView.loadUrl("file:///android_asset/a.html");

问题是，调整大小的iFrame有时太大，有时太小

我用安卓2.2在galaxy s上测试了它，所有的帧都变小了（最后被切掉），而在另一台安卓4.0.4的设备上，所有的帧都变大了（增加了空白）

如果我删除

webSettings.setJavaScriptEnabled（true）galaxy s中的问题消失了，但在第二台设备中，帧根本不会调整大小

您需要为iframe标记中的onload处理程序设置侦听器，每个侦听器一个，并在加载iframe而不是主体时调整每个侦听器的大小
var iframe = document.getElementById('yourIF');
var iframeWin = iframe.contentWindow || iframe.contentDocument.parentWindow;
iframe.style.height = (iframeWin.document.documentElement.scrollHeight || iframeWin.document.body.scrollHeight) + "px";
